Measure low ammonia concentrations with the MH2000-NH3 Low Range gas detector. This portable electrochemical instrument uses an internal sampling pump and is offered as separate 0-10 ppm and 0-20 ppm versions. It is intended for ambient-air or odor-environment NH3 concentration checks where one of these measuring spans fits the task. Choose one range when ordering; each option is a single-gas ammonia detector.
Choose Between 0-10 and 0-20 ppm
The 0-10 ppm version has a lower maximum measuring span; the 0-20 ppm version covers a broader low-concentration interval. Select the range for the expected NH3 concentration and the measurement procedure. The range label identifies the version supplied. A detector ordered in one range does not automatically switch to the other range.
This instrument reports ammonia concentration. It does not measure general odor intensity or identify all gases contributing to an odor. Keep the target gas and the expected concentration explicit when selecting the instrument and sampling arrangement.
Pump Sampling and Adjustable Alarms
The internal pump draws a sample to the electrochemical sensor, with flow up to 1 L/min and ten adjustment settings. The LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. The operating interface supports English and Chinese, and concentration can be displayed in ppm or mg/m³.
Two alarm stages have adjustable setpoints. Sound, light and vibration outputs include an 85 dB sound alarm and blue low-alarm/red high-alarm lights. Temperature and pressure compensation, self-check, zero calibration and factory-reset controls support instrument setup. Use the supplied instructions and the procedure for the intended measurement.

Recording and Optional Sampling Equipment
Data logging and PC export are optional and are not included in this base configuration. If stored measurement records are needed, ask about the recording option before ordering. Filters, drying accessories and high-temperature probes are separate sampling choices; their suitability and inclusion depend on the intended arrangement.
The instrument weighs 300 g and uses a rechargeable lithium-polymer battery. Gallery photos illustrate the shared housing and carrying-case views. The image with two instruments does not represent a two-unit package, and a connected cable does not establish that PC data export is included.

My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
Works as described.
